In the middle of summer, when outside temperatures rise above 30 °C, many households still heat hot water with oil, gas, or even wood boilers. While heating rooms is unnecessary during this period, these bulky systems are often kept running just to supply hot water.
But what if you could switch off the boiler, save enough for a family holiday, and only step into the boiler room for a cold drink? Instead of starting up an oversized heating system just for hot water, you can rely on a modern, purpose-built solution – a heat pump water heater.
How It Works – and Why It’s Most Efficient in Summer
A heat pump water heater extracts heat from the surrounding air and, using a compressor, converts it into energy to heat your water. The warmer the air, the more efficiently it works. That’s why in summer, it achieves higher efficiency with minimal electricity consumption.
Compared to conventional electric water heaters, a quality heat pump can reduce energy use by up to 75% – a saving you’ll see on your monthly bills and in your home’s carbon footprint.
Why Replace a Boiler or Water Heater?
Electric water heaters often consume around 3,400 kWh per year, resulting in high running costs and roughly 1,300 kg of CO₂ emissions – about the same as driving a car for a year.
Oil boilers are even more expensive and particularly inefficient in summer, when systems run at poor efficiency and produce the highest household emissions.
A heat pump water heater, by contrast, needs only ~850 kWh per year to deliver the same amount of hot water – cutting energy use by up to 75% without sacrificing comfort.
Hot Water and Cooling in One
The KRONOTERM hot water heat pump not only heats water but also gently cools the room it’s installed in, such as a pantry, basement, or laundry room. In summer, it works like a passive air conditioner, reducing room temperature while heating water.
When connected to air ducts, the system (with KRONOFLEX technology) allows you to direct cooled air where you need it most. That means you get hot water plus free cooling – all with one device.
Perfect Match for Solar PV Systems
Summer is when solar panels generate the most electricity. A heat pump water heater is the ideal way to use this surplus power. Instead of exporting excess electricity to the grid, you can store your solar energy in the form of hot water, achieving nearly zero-cost operation. Quiet, efficient, and sustainable.
Let Your Furnace Take a Summer Break
Your furnace deserves a holiday too. Replace outdated and inefficient water heating methods with a modern, eco-friendly alternative. Your wallet, the planet, and your summer lifestyle will thank you.
